Thermostat Power
The thermostat can be powered by either 24VAC from the HVAC system or from four (4) type AA
internal baeries. DO NOT use this thermostat for line voltage controls (120/240VAC).
The C Wire
If the 24VAC common wire (usually blue) is present and is connected to 24VAC common at the HVAC
system end, the thermostat can be powered from the HVAC system. If there is no common wire,
baeries are required.
24VAC Power
Powering the thermostat with 24VAC power requires both the 24VAC “C” common wire (typically a
blue wire) and the 24VAC ”R” return wire (typically a red wire).
Baery Power
Powering the thermostat from baeries does not require a “C” wire connecon.
DO NOT install baeries if the thermostat is powered by 24VAC. They are NOT required for backup.
If the thermostat is powered by baeries, the thermostat will operate for approximately (2) two
years on four (4) AA Alkaline baeries depending on the frequency of user operaons and backlight
operaon. Always use Alkaline baeries and replace them in complete sets of four (4).
Z-Wave Operaon when Baery-Powered
IMPORTANT: When the thermostat is installed on a Z-Wave network, while it is baery
powered, it will NOT work as a Z-Wave repeater.
Remove Existing Thermostat
• Turn the thermostat power o. This is usually done at the heang/cooling system or circuit
breaker panel.
• Remove the cover of old thermostat to expose the wiring terminals.
• Take a picture of the wiring terminals and wires before disconnecting them!
• Mark the exisng thermostat wires with the labels (not included) according to the terminal
markings. Some installaons may have addional wires not shown in the example illustraon
below (Y1, Y2, W1, W2, O,B).
• Use the thermostat terminal “names/marking” (not the wiring color) to mark the wires.
• Remove the old thermostat base.
CAUTION: When removing thermostat, don’t let the wires slip into the wall and
don’t let the wires touch each other.
• If the old thermostat was a mercury style thermostat, dispose of it properly as described below.
Figure 2. Label Wire Terminals
Note: Taking a picture is crical if problems are encountered. This will allow reinstallaon of the old
thermostat and help with troubleshoong later if needed.
Terminal Typical Wire Color Function
Y YELLOW Cool
W WHITE Heat
G GREEN Fan
R RED 24VAC Return
CBLUE
24V Common (typically BLUE). When the wire is present,
the thermostat can be powered without baeries. When
the wire is absent, the thermostat must be powered by
baeries if 24VAC is present across the R&C wires
Wiring Colors
While the thermostat terminal markings are intended to match the wire color (R=RED, G=GREEN,
W=WHITE, Y=YELLOW), be sure to follow the terminal marking when marking the wires, even if the
wire color doesn’t match.
WARNING: If the exisng thermostat is a mercury-containing device, it must be
disposed of in compliance with federal, state and local regulaons. Many states and/
or local agencies have collecon/exchange programs or hazardous waste collecon
programs for mercury-containing-devices. For more informaon, see the U.S.

Thermostat Setup Menus
The thermostat must be set up for the correct HVAC system type for proper operaon.
Preset HVAC System sengs
The thermostat is preset for the following typical HVAC system conguraon:
• HVAC system type: Standard gas/electric
• HVAC fan type: Gas heat
• HVAC heang stages: One
• HVAC cooling stages: One
If the thermostat is installed on this type HVAC system, the System Setup does not need to be
changed.
If installed on a Heat Pump HVAC system or any HVAC conguraon other than the preset sengs,
change the sengs in the SYSTEM setup menu to match the HVAC system.
Note: To conserve energy, the thermostat backlight turns o aer a short me of no acvity. The
rst buon touch turns on the backlight (but does not iniate any acon). Touch the buon again
to iniate the acon desired. If the backlight is already on, buon touches work with the rst touch.
Wait Mode
The thermostat has a Minimum O Time (MOT) delay aer any heang or cooling cycle ends. This
delay prevents rapid heang/cooling cycles and also provides “short cycle protecon” for the system
compressor. This delay may be noceable when you change a setpoint, and it does not respond
immediately due to the MOT delay mer prevenng the system from restarng. The MOT delay me
can be adjusted in the Advanced Sengs menu of the thermostat, but there is a minimum of ve
minutes delay to assure compressor protecon.
Minimum Run Time (MRT)
The thermostat has a Minimum Run Time delay aer the start of any heang or cooling call. This
minimum run me assures even heang and cooling cycles. The MRT will keep the system on, even if
it reaches the setpoint room temperature or if you change the setpoint to a temperature that would
sasfy the call unl the MRT expires. The MRT can be adjusted in the Advanced Sengs menu of the
thermostat.
Note: The MRT delays are shown by ashing heat or cool icons on the display.
Frost Protecon
The thermostat has a frost protecon feature built in. It forces the highest possible heat stage to turn
on in order to prevent room temperature from becoming too cold. Once enabled, frost protecon
acvates automacally at 41°F (5 °C) and deacvates at 48 °F (8 °C), regardless of System Mode and
Heat/Cool Set Point. To acvate the feature, go to Advanced Systems Sengs Menu (p17).

• For Changeover with Heang systems, use the  buons to change to WITH HEAT.
• Touch FAN (Select) to set.
• Touch MODE (Done) to exit.
Not sure which type Changeover system? Check the exisng thermostat connecons to help
determine this. If the original system had an orange wire connected to an “O” terminal, then you
have a “changeover with cool” system. If there was a brown wire connected to a “B” terminal, then
you have a “change over with heat” system. Set the Changeover seng accordingly.
Note: If heang turns ON when cooling is expected or vice versa, switch the “Changeover Type” to
the opposite seng.
HUMI
The SETUP menu is used to set the humidicaon type, if used. The following setup opons will be

Seng the System Mode
Figure 20. Setting the System Mode
System Modes
• Off*: System is o. No heang or cooling will come on. If system was on, it will turn o
immediately.
• Heat: Only heang will occur.
• Cool: Only cooling will occur.
• Auto: Heang or cooling will acvate according to the heang and cooling setpoints. The
system will automacally switch between heang and cooling modes as needed to maintain
the setpoints.
* = Default
Special Heat Pump Mode: Emergency Heat
An addional system mode, “Heat-E” for Emergency Heat will be displayed if the HVAC System Type
is set to Heat Pump. If there is a compressor failure with the Heat Pump system, seng the mode
to Emergency Heat will allow the supplemental Aux Heat to acvate rst whenever there is a call
for heang. It also disables the compressor output to prevent further damage to the HVAC system.
CAUTION! Emergency Heat should only be used for emergencies unl the HVAC
system can be repaired. Running the system in Emergency Heat mode is commonly
the most expensive mode since only the electric heat strips are being used instead of
the more ecient heat pump compressor.
Seng the Heang or Cooling Temperature Setpoint
To change the setpoint, touch the  buons. The screen will switch to the setpoint change
screen, and show the current setpoint of the current heang or cooling mode. Adjust the setpoint
temperature up or down with the  buons.
Note: When in the Setpoint Change screen, pressing the MODE buon will switch the setpoint being
displayed between the Heang* and Cooling setpoints.
* = Default
Figure 21. Accessing Setpoints
Figure 22. Setpoint Change Screen
Automac Setpoint Push
The cooling setpoint cannot be set below the heang setpoint. The thermostat will “push” the heang
setpoint lower if the cooling setpoint is set below the current heang setpoint. A three (3) degree
separaon is maintained between the heang and cooling setpoints. The same is true for raising the
heang setpoint above the cooling setpoint. The thermostat will “push” the cooling setpoint up to
maintain the 3 degree separaon.
Frost Protecon
Frost Protecon is used to prevent rooms from being too cold. Once enabled, frost protecon acvates
at 41 °F (5 °C) and stops at 47 °F (8 °C) regardless of System Mode and Heat / Cool Set Point. To acvate
the feature, go to Advanced Systems Sengs Menu (p17).

Z-Wave Information
• This thermostat can be operated in any Z-Wave network with other Z-Wave cered devices
from other manufacturers. All non-baery operated devices within the network will act as
repeaters regardless of vendor to increase reliability of the network.
• Z-Wave is an Inter-operable two-way RF mesh networking technology designed for use with a
Z-Wave gateway/controller and other Z-Wave enabled devices.
Advanced Z-Wave® Information
This secon is for the advanced user who has knowledge of the Z-Wave™ Command Classes. Please
note that the thermostat operates in Frequently Listening Receiver Slave (FLiR) mode, when it is
baery-powered.
Support for Associaon Groups
This thermostat supports Group 1, which can hold up to 5 nodes.
Group 1 Associaon is the default status report channel in Z-Wave+ lifeline requirements. Group 1
Alerts nofy an associated device of a thermostat generated change. Thermostat generated changes
are changes that originate at or by the thermostat.
The following informaon is included in the lifeline report:
Low Voltage Alarm
When baery power is down to 30% or lower, the thermostat will send a low voltage alarm to the
Z-Wave Controller and display the low baery icon on the LCD.
Z-Wave Indicator
The thermostat's Z-Wave indicator will display when it receives Indicator CC from ZWave controller/
gateway.
Basic CC and Thermostat Mode CC
Basic Set On/O is mapped to Thermostat Mode CC. Z-Wave controller/gateway sends a Basic Set CC
with value 0 (O) to set O mode, and sends value 255 (On) to set Auto mode.
Energy Saving Mode
Energy Saving Mode is only available for those with a compable Z-Wave controller/gateway that
supports energy saving mode.
The thermostat can be put into energy saving mode through ZWave by seng Thermostat Mode to
